Definitions

  • the present invention generally relates to ultrasound diagnostic systems, and more particularly to an apparatus and method for displaying a color flow image in an ultrasound diagnostic system.
  • EP-A-0 797 106 discloses a method of producing 3-dimensional ultrasonic images of flow or motion.
  • the 3-dimensional image is formed by combining a tissue image with a blood flow image.
  • an ultrasound diagnostic system projects ultrasound signals from a surface of a target object toward a desired part within the target object. This is to obtain an ultrasound image of a soft tissue or blood flow by non-invasive means through using information of ultrasound echo signals from the target object.
  • the ultrasound diagnostic system is advantageous since it is small in size and fairly inexpensive.
  • the ultrasound diagnostic system is capable of providing real-time display and is highly safe without any dangerous side effects such as exposure to X-rays, etc.
  • it is extensively utilized for diagnosing the heart, abdomen and urinary organs, as well as being widely applied in the fields of obstetrics, gynecology, etc.
  • the ultrasound diagnostic system forms ultrasound images of various modes (e.g., B-mode, M-mode, etc.) based on the ultrasound echo signals reflected from the target object. Also, the ultrasound diagnostic system can provide a color flow image, which indicates the velocities of a moving target object and scatters.
  • the ultrasound diagnostic system displays the velocity and direction of blood flowing within a moving object (e.g., heart, blood vessel or the like) with various colors based on the Doppler shift of an ultrasound signal. For example, the conventional ultrasound diagnostic system indicates the blood flowing toward the transducer of the probe with a red color, while indicating the blood flowing backward from the transducer of the probe with a blue color. Furthermore, the conventional diagnostic system indicates a rapidly flowing blood with a light color, while indicating a slowly flowing blood with a dark color.
  • the conventional diagnostic system displays the color Doppler image, which indicates the velocities of the moving target object and the scatters, on a 2-dimensional level, there is a problem in that a person unskilled in the conventional diagnostic system cannot accurately analyze the 2-dimensional color Doppler image.
  • the conventional ultrasound diagnostic system superposes a plurality of 2-dimensional ultrasound images to provide a 3-dimensional color Doppler image. This is so that the above unskilled person can easily examine the target object through the displayed 3-dimensional color Doppler image.
  • the 2-dimensional color Doppler images indicating different blood flows are superposed, then the colors indicating the blood flows are displayed while the images are superposed. Therefore, there is a problem in that the conventional ultrasound diagnostic system cannot provide accurate information of the blood flows.
  • an apparatus for displaying a color flow image in an ultrasound diagnostic system according to claim 4.
  • Fig. 1 is a block diagram showing an ultrasound diagnostic system 100, which is constructed in accordance with the preferred embodiment of the present invention.
  • the ultrasound diagnostic system 100 includes a probe 110, a beam former 120, an image processor 130, a memory 140 and a display unit 150.
  • the probe 110 includes a 1-dimensional or 2-dimensional array transducer 112.
  • the transmit signals which are appropriately delayed to form a focused ultrasound beam in the beam former 120, are transmitted to the array transducer 112 and the focused ultrasound beam is transmitted along a scan line of a target object (not shown).
  • the probe 110 receives ultrasound echo signals reflected from the target object and converts the ultrasound echo signals into electric signals (hereinafter referred to as reception signals).
  • reception signals are transmitted into the beam former 120.
  • the beam former 120 controls the delay of transmit signals to be transmitted to the array transducer 112 in the probe 110 such that the ultrasound signals outputted from the array transducer 112 are focused on a focal point. Further, the beam former 120 focuses the reception signals received at the array transducer 112 included in the probe 110 in consideration of the delays with which the ultrasound echo signals arrived at each transducer.
  • the image processor 130 sequentially superposes a plurality of 2-dimensional color flow images, which are formed based on the reception signals outputted from the beam former 120, to form a 3-dimensional color flow image containing blood flow images.
  • the 3-dimensioanl color flow image includes a plurality of image regions and each region is differently colored.
  • the image processor 130 performs a transparency treatment for a blood flow image region selected by a user to have a predetermined transparency.
  • the 3-dimensional color flow image, which is processed. in the image processor 130 may be stored in the memory 140 or displayed on the display unit 150 according to the selection of the user.
  • Fig. 2 is a flow chart showing the operation of the image processor, which is constructed in accordance with the present invention.
  • the image processor 130 forms the plurality of 2-dimensional color Doppler image based on the focused reception signals outputted from the beam former 120 at step S110.
  • the reception signals include color information of the target object.
  • the image processor 130 checks whether a 3D mode is selected at step S120. If it is determined that the 3D mode is selected at step S120, then the image processor 130 sequentially superposes the plurality of 2-dimensional color flow images so as to form the 3-dimensioanl color flow image at step S 130.
  • the 3-dimensional color ultrasound image 310 includes a plurality of image regions and each region is differently colored.
  • the 3-dimensional color ultrasound image 310 and color maps 322 and 332 corresponding to blood flow images 321 and 331, which are examples formed in the image processor 130, are shown in Fig. 3 .
  • the image processor 130 checks whether a region, which is processed with transparency, is selected based on selection information inputted from the user at step S 140.
  • the selected region may correspond to a region, which the user does not wish to observe.
  • the selection of the region is carried out by selecting one of the color maps 322 and 332 or one of the colors within the color maps 322 and 332.
  • the image processor 130 performs the transparency treatment for a color of a blood flow in the selected region so as to have a predetermined transparency at step S 150. For example, if the color map 322 corresponding to the blood flow image 130 is selected as a region to be transparentized, then the image processor 130 assigns a transparent color having the predetermined transparency to the color indicating the blood flow image 321 and color map 322. Consequently, the color indicating the blood flow image 321 and color map 322 are transparentized, as shown in Fig. 4 .
  • the region selected by the user is transparentized as a region that is not to be observed.
  • the regions, which are not selected by the user may be set as regions that are not to be observed. This is so that the transparency treatment may be performed to the regions with the exception of the selected regions.
  • the transparency treatment is selectively carried out for colors corresponding to the blood flow images that are superposed, the blood flow image to be observed can be separately displayed. This is so that the user can accurately examine the blood flow image that the user wishes to observe.
